<p>A method, an apparatus, and a system for Internet Protocol (IP)/optical convergence are provided. The method includes the following steps. A request for establishing a user network interface (UNI) is sent to an optical network device. A generalized multiprotocol label switching (GMPLS) label returned by the optical network device is received. The GMPLS label is converted into a virtual local area network (VLAN) identifier (ID) (VLAN ID) of an Ethernet sub-interface, and the Ethernet sub-interface is adopted for communication. By converting the GMPLS label into the VLAN ID of the established Ethernet sub-interface, the common Internet/multiprotocol label switching (MPLS) can be applied in GMPLS UNI, so as to realize the IP/optical convergence.</p> |
